Xray REALITY over RAW / TCP

Cryptographic resistance profile and Deep Packet Inspection (DPI) evasion analysis

SNI: Low-Profile SNI (Optimal for Reality) Port 443 (Standard HTTPS) uTLS: 13778572 (Active)

This node utilizes RAW / TCP transport with Xray REALITY. It applies TLS-in-TLS masking to eliminate identifiable proxy signatures, making the handshake look like a legitimate browser connection.

Network Port Analysis: Port 443 is the universal standard for secure HTTPS traffic. Firewalls and ISPs cannot block it without disrupting regular web access.

SNI Masking Analysis (www.oracle.com): Masked under a low-profile external domain (www.oracle.com), which effectively reduces detection risk from automated DPI heuristics.

uTLS Handshake Security Analysis (13778572): Emulating 13778572 TLS parameters to protect against passive fingerprinting.

Flow Technology: Flow "xtls-rprx-vision" (XTLS Vision Seed) dynamically obfuscates packet padding, preventing DPI systems from measuring TLS ClientHello length patterns.

Client Handshake Masking (uTLS): Emulating 13778572 TLS parameters to protect against passive fingerprinting.

REALITY Cryptography: Public key (pbk) pinned on server • Short ID (sid: e726fb) validated for session authorization
